nm-applet leaks massive memory

After upgrading to Ubuntu 12.04, I noticed nm-applet would leak huge memory when I leave my machine running overnight (or more). I would notice the machice is crawling, and top would reveal 50%+ of 4GB memory taken by nm-applet.

I figured 2GB for the applet is tad too much ... It happened more than couple of times, I think.

See attached screenshot of top output.

Also, simple "killall nm-applet" won't kill it. I had to do "killall -9 nm-applet" to restore the memory and restart nm-applet manually.

Ubuntu: 12.04

$ dpkg -l | grep network-manager
ii network-manager 0.9.2.0+git201201101813.0b30200-0ubuntu2 network management framework (daemon and userspace tools)
ii network-manager-gnome 0.9.2.0+git.20120126t000800.5151959-0ubuntu1 network management framework (GNOME frontend)
ii network-manager-pptp 0.9.0-0ubuntu2 network management framework (PPTP plugin core)
ii network-manager-pptp-gnome 0.9.0-0ubuntu2 network management framework (PPTP plugin GNOME GUI)

It's likely going to happen again - if there is anything I could help collect when it happens again, I would be happy to do so.
